Dale,
Nobody suggested that the switch failure would be a flight stopper.  The switch is
there.  The issue I thought I was addressing was fastening it to the throttle so
it would bypass any time full throttle was applied.  My position was and is that
forgetting to bypass for TO or T&G isn't a flight stopper, and as far as anyone
knows, is not a problem at all.  I am ambivalent about installing complex
solutions to non-problems.
PVORT again I'm afraid ... Jim S.

Jim,

    While addition of any component adds complexity and additional
opportunities for failure, we also have to look at the failure modes.  If the
additional wiring is done well, shorts and opens of the actual wire should be
nil.
That leaves the switch - two failure modes, stuck open and stuck shorted.  If
it's stuck open, the controller has the same lag that's being experienced now.
  If it's stuck closed, the pump will run all the time until you land and
disconnect it.  I wouldn't think that either event is a flight stopper.
